Forms when atoms share electrons and is the strongest type of chemical bond?

• A. Ionic bond
• B. Hydrogen bond
• C. Covalent bond
• D. Metallic bond

Answer: (C)

Sharing electrons to fill outer shells creates a covalent bond. This happens when atoms, usually nonmetals, come close and pair some of their electrons so both can count those shared electrons toward a full outer shell. The result is a strong, localized attraction between the two nuclei and the shared electron pair. Bond strength increases with the number of shared pairs—single, double, and triple covalent bonds differ in how many electrons are shared, with triple bonds being the strongest among them. This direct, electron-sharing mechanism gives covalent bonds their notable strength in many molecules and network solids. By contrast, ionic bonds form from transferring electrons to create charged ions that attract each other, hydrogen bonds are weaker interactions between molecules, and metallic bonds involve a lattice of positively charged cores with a sea of delocalized electrons rather than discrete shared pairs. So the form that involves sharing electrons and is typically the strongest type of chemical bond is covalent bonding.
